Abstract

In this paper,study on the treatment of coking wastewater by Fenton reagent was carried out.The factors having effect on COD removal of coking wastewater by Fenton reagent,such as H_2O_2 dosage,[Fe~(2+)]/[H_2O_2],pH value and reaction temperature,were discussed.Then the operating conditions were determined under which COD removal of coking wastewater was up to 89.9%.Based on the above experiments,the effect of H_2O_2 putting way on COD removal was discussed.The results showed that if hydrogen peroxide was put in batches,the treatment effect will be better.
